Radio communication over a distance of at least 2 light-seconds using the Moon as reflector.
Anyone interested in actually talking to him/herself? We can do that - you're welcome.
- Preface in German language:
Project Moonbounce's aim is to provide the visitors of 2011's Chaos Communication Camp some interesting insights into amateur radio in general and into one of its most spectacular varieties in particular. Earth-Moon-Earth (EME, Moonbounce) radio communication directly on the campsite and for everyone's amazement. Since the camp's language is mostly English due to the very international audience, this site is as well.
This site is used for organizational purposes. Pse add all infos/thoughts/help offers/donations and whatever you think might help us to reach our goal!
- We will work in the 2m Band using 2 long Yagi Antennas and a high power amplifier.
- Togehter with the Chaoswelle we will also be partaking in all other Hamradio Activities on the Camp.

After collecting all equipment a testing setup will be created to check if all components are working, if nothing is missing and if we can improve our setup.
At least one truck and one big van with trailer.

Working the Moon
There will be a special event callsign for the Camp that we can use. An alternative would be using home-callsigns with DL prefix.
Conds - Space-Weather/Moon constellation
- Moon is full which does not really matter but looks nice :-)
- Earth-Moon distance: 395000 km - could be closer but we're not going to change that.
- Path in the sky at Finowfurt...
